[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for displaying a rotor in a display unit of a centrifuge that can be used by exchanging a plurality of rotors.
[0002]
[Prior art]
Recent centrifuges have many functions added to improve usability and use LCD (Liquid Crystal Display) that can display more information. There are an increasing number of cases in which the centrifugal effect (g × sec) is displayed, or a multi-function such as a function for calculating a rotational speed and a separation time from these numerical values and a function for displaying a list of usable rotors.
[0003]
Among these, when displaying the list of rotors on the display unit, the data stored in the ROM built in the centrifuge is classified in advance according to the type of rotor and arranged in the order of the maximum rotational speed. Is displayed on the LCD or the like when the rotor list display is selected. When the user searches for the target rotor from this list and selects it from the input unit or the like, information on the rotor is extracted, and the above-described calculations and various functions can be utilized.
[0004]
On the other hand, in this type of centrifuge, since the rotor is replaced and used according to the amount and type of the sample, the shape of the tube into which the sample is put, and the separation conditions, the rotor has the same rotational speed as the rotor. Rotors with different dimensions and rotors with different maximum speeds even though the rotors have the same shape and dimensions are being developed and put on the market one after another. For this reason, users often purchase newly developed and released rotors, and centrifuges use a control panel to control the rotor, such as the maximum rotational speed of the rotor, the rotational radius of the rotor, the rotor model name, and the rotor identification data. Some have a function of inputting information and storing it in the control unit of the centrifuge body. For example, the CS150GX / 120GX / 100GX centrifuges that Hitachi Koki Co., Ltd. has been selling since 1996 have the function to input and store information on the newly purchased new rotor and calculate the centrifugal acceleration. It is. However, these registration functions merely create a situation where a new rotor can be used, and the new rotor input by the user from the operation panel is not added to the rotor list and displayed. A centrifuge that displays an additional rotor in a list is also provided, but it is merely a method of registering with a specific name (for example, rotor (1), rotor (2)).
[0005]
[Problems to be solved by the invention]
When the list of rotors is displayed as described above, and the user can easily select the required rotor, the operability can be improved. However, there is a problem that the list of rotors registered in advance in the centrifuge main body is not displayed, and the rotors input and stored by the user cannot be displayed later.
[0006]
In addition, for a list of specific names (for example, rotor 1 and rotor 2 as described above), it is not clear which rotor is registered with which name other than the registrant, or it is specified somewhere. There was a problem that had to be.
[0007]
An object of the present invention is to provide a centrifuge that is easy to operate by solving the above problems and displaying information on a rotor added by a user in a rotor list. In addition, the display method of the added rotor is devised to provide an easier-to-use rotor list function.
[0008]
[Means for Solving the Problems]
The above object is achieved by displaying both the rotor input and stored by the user from the operation panel and the rotor previously stored in the ROM on the display unit.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing a control device for a centrifuge in this embodiment. The operating conditions input from the switch unit 12 of the operation panel 1 are stored in an Electrically Erasable and Programmable Rom (referred to as an EEPROM, hereinafter referred to as RAM) that is a first storage unit that can be read and written via the microcomputer 2 and displayed. Part 11 is displayed. The RAM 4 is configured so that data is retained by the battery 5 even when the power of the centrifuge is turned off.
[0010]
Information on a plurality of rotors that can be used in the centrifuge (maximum rotation speed, rotor rotation radius, rotor model name, rotor identification data, etc.) is stored in advance as a second storage unit in a ROM 3 rotor A information storage unit 3a and rotor B. It is stored in the information storage unit 3b,.
[0011]
Now, when the centrifuge is operated, the microcomputer 2 compares the rotor identification data stored in the ROM 3 or RAM 4 with the rotor identification data and the signal of the rotor identification sensor 8 to identify the rotor 6 and display it on the display unit 11. The rotor type name is displayed, and it is checked whether the rotational speed input from the operation panel 1 exceeds the maximum rotational speed of the rotor based on information on the rotor 6, or g calculation is performed.
[0012]
On the other hand, when using a rotor (usually an old rotor) that does not have a mark (not shown) corresponding to the rotor identification sensor 8, when the rotor identification sensor 8 fails, and when the rotor is used as a centrifuge Without setting (when pre-cooled with a sample in a refrigerator, etc.), the centrifugal acceleration is calculated from the rotation radius of the rotor and the set rotation speed, or conversely, the rotation speed is calculated from the centrifugal acceleration. Since the rotor cannot be automatically identified in some cases, the desired rotor identification number is selected from the switch section 12. It is necessary to extract the unique information of the rotor (usually, when there is no information, the safety device works and cannot operate). However, this identification No. It is not realistic to memorize each time, and to read the instruction manual for each use.
[0013]
Therefore, the display unit 11 of the centrifuge has a function of displaying a list of usable rotors. When the user presses a specific key (for example, a rotor key) of the switch unit 12, a list of rotors can be displayed, and a desired rotor can be easily found and selected. However, since the rotors displayed in the list are limited to those stored in the ROM 3, when a new rotor not stored in the ROM 3 is purchased, the user inputs information about the rotor from the switch 12. The rotor information storage unit 4a or 4b to 4g of the RAM 4 can be stored in any area. Information on the rotor input from the operation panel 1 includes the maximum rotation speed, the rotation radius of the rotor, the rotor model name, and the rotor identification number. Etc.
[0014]
When a user inputs information on a new rotor, an environment in which information about the rotor can be extracted is created, so that the new rotor can be used, and when the rotor key of the switch unit 12 is pressed and the rotor list is displayed, the microcomputer 2 reads the ROM 3 The rotor type name information is taken in from the rotor information storage units 3a, 3b,... And the rotor type name information is also taken from the rotor information storage units 4a, 4b,. If displayed, the model name of the newly registered rotor that could not be displayed in the past can be added to the list and displayed.
[0015]
Next, a display method will be described. In the description, a rotor sold by Hitachi Koki Co., Ltd. will be taken as an example, and a description will be given assuming that the user newly inputs a rotor named R10A3, R10S2, R12A5 from the operation panel 1. The user must follow a certain procedure to obtain information such as the R10A3, R10S2, and R12A5 rotor model names, maximum rotational speed, rotational radius, etc. and identification number. Is input from the switch unit 12 and stored in the rotor information storage units 4a, 4b,. Then, when the rotor list screen is displayed by pressing the switch part 12 rotor key, the microcomputer 2 also displays the newly registered R10A3, R10S2, and R12A5 rotor model names together with the rotor model names registered in the ROM 3. There are, however, a list of rotors that are difficult to see if they are arranged in random order. An example of this rule is described below. As shown in FIG. 5, the first letter is a symbol 51 indicating a suitable centrifuge body. The next number means the maximum rotational speed 52 of the rotor, and the value multiplied by 1000 is the maximum rotational speed. The next letter represents the rotor type 53 and is generally classified as a fixed angle rotor, horizontal rotor, vertical rotor, continuous rotor, special rotor, etc. In this embodiment, A is a fixed angle rotor, S is a horizontal rotor, and V is vertical. It is classified by English letters such as rotor. The next number or letter is the rotor number 54. The number after the rotor type name on the rotor list display screen. Is the rotor identification number. This is because the rotor can be selected by inputting a number from the switch unit 12.
[0016]
From the above, even when a newly registered rotor is added to the list display, it can be displayed easily if it is displayed according to this rule. FIG. 2 is an example displayed according to this rule. When there are many types of rotors, the display is limited to several pages as in this embodiment due to display area restrictions. FIG. 2 (a) is the first page of the rotor list display screen, and FIG. 2 (b) is the second page. FIG. 2C shows the third page, and a page break can be made by pressing a specific key of the switch section 12. The newly registered R10A3, R10S2, and R12A5 rotors are added and displayed in order on the second and third pages, respectively.
[0017]
In order to display in accordance with the rules as described above, the microcomputer 2 stores the rotor model name stored in the ROM 3 in advance and the rotor information stored in the rotor information storage units 4a to 4g of the RAM 4 from the operation panel 1 by the user ( R10A3, R10S2, R12A5) are classified according to rotor type 53. Next, the rotor model names classified according to the type of rotor are sorted in order of the maximum rotational speed according to the maximum rotational speed 52 of the rotor. When there are a plurality of rotors having the same rotational speed, they are arranged in the order of the rotor number 54. Thus, when the rotor type names are displayed by the microcomputer 2, the rotor type name (R10A3) stored in the rotor information storage unit 4a is displayed on the rotor display unit 22 and stored in the rotor information storage unit 4b. The rotor model name (R10S2) can be displayed on the rotor display unit 23, and the rotor model name (R12A5) stored in the rotor information storage unit 4g can be displayed on the rotor display unit 21.
[0018]
Therefore, although newly registered rotors can be displayed according to the rules, the user is unlikely to purchase and use all the rotors displayed in a list, and usually only a few rotors are purchased. That is, it is normal that only a part of the rotor list is actually used. On the other hand, the newly purchased rotor is definitely owned and the usage frequency is relatively high, so if you simply list it according to the rules, the newly registered rotor will enter between unused rotors, and it will be difficult to see. In some cases, there is also a drawback that it cannot be found without a page break.
[0019]
Therefore, as shown in FIGS. 3A to 3C, the rotor model name input from the operation panel 1 and stored in the RAM 4 is displayed first, and then the rotor model name stored in advance in the ROM 3 is displayed. If you do this, you can improve usability. The microcomputer 2 first looks at the contents of the rotor information storage unit 4a of the RAM 4, and if rotor information is stored, the rotor model name R10A3 (No. 45) of the rotor information storage unit 4a is displayed in the rotor display unit of the display area 31. If the rotor information is stored in the rotor information storage unit 4b, the rotor model name R10S2 (No. 4) of the rotor information storage unit 4b is displayed in the rotor display unit 312. indicate. Thereafter, the same operation is performed, and the rotor model name R12A5 (No. 1) of the rotor information storage unit 4g is displayed on the rotor display unit 313. As a matter of course, when there is no rotor information in the rotor information storage section, the rotor model name is displayed together. Next, the rotor type names that are classified in advance in the ROM 3 according to the type of rotor and stored in order of the maximum rotational speed are displayed. In the present embodiment, the rotor model name with the highest maximum rotation speed of the fixed angle rotor is displayed from the rotor display unit 314 of the display area 31, and when the display of the display area 31 is finished, it is moved to the display area 32 and displayed. When the rotor list screen is changed to the rotor list screen 2, the rotor type name following the display area 32 is displayed as described above. Similarly, when the display area 33 is displayed and the display of the fixed angle rotor is completed in the middle of the display area 34, the rotor type is different, so the rotor type name of the horizontal rotor is displayed instead of the display area 35. .
[0020]
Alternatively, as shown in FIG. 4A, when the display area 31 is used exclusively for displaying the rotor list of the rotors input from the operation panel 1 and the rotor stored in the ROM 3 is displayed from the display area 32, the operation panel 1 Can be displayed separately from the rotor model name input from the memory and stored in the RAM 4 and the rotor model name stored in the ROM 3 in advance. In this case, when there is no rotor information input from the operation panel in the RAM 4, the rotor type name stored in the ROM 3 is displayed from the display area 31.
[0021]
Also, as shown in FIG. 4 (b), the rotor type names from the rotor information storage units 4a to 4g of the RAM 4 are classified according to the type of rotor and displayed in order of the maximum rotational speed, so that it is easy to see and easy to use.
[0022]
Further, a function of separately displaying the types of rotors is provided. For example, when a fixed-angle rotor is selected and displayed, the rotor type stored in the rotor information storage units 4a to 4g of the RAM 4 as shown in FIG. Only the fixed-angle rotors having the names may be displayed in the display area 31 in the order of the maximum rotational speed, and the rotor type names stored in the ROM 3 may be displayed in the display area 31.
[0023]
As described above, it is possible to display a list of rotor model names and the like input by the user from the switch unit 12 of the operation panel 1 and to display them first when displaying a list of rotors, or to input from the switch unit 12. Since the rotor registered in the RAM 4 and the rotor stored in the ROM 3 can be displayed separately, it becomes easy to find the target rotor from the rotor list display, and the usability can be further improved. become able to.
[0024]
【The invention's effect】
According to the present invention, when displaying a list of rotors, a user purchases a rotor, inputs information about the rotor from the operation panel, and can display a list of registered rotors together. Can improve usability. In addition, by displaying the registered rotors at the beginning of the list display, it is possible to easily find the type name of the rotor that is frequently used and registered by the user through the operation panel, and the operability can be improved. .
